Device, method and system for detecting micro gap based on industrial equipment

Abstract

The embodiment of the invention discloses a device, a method and a system for detecting a micro gap based on industrial equipment. A lens tube and a duel-light source assembly are included; the lower end of the lens tube is connected with the duel-light source assembly; the duel-light source assembly comprises an upper annular light source assembly and a lower annular light source assembly; and thus, irradiation of different light sources is realized for image processing on a PCB or a micro gap to-be-detected product; and subsequent industrial equipment-based micro gap detection is carried out. The subsequent industrial equipment-based micro gap detection device comprises the lens tube and the duel-light source assembly; the lower end of the lens tube is connected with the duel-light source assembly; and the duel-light source assembly comprises the upper annular light source assembly and the lower annular light source assembly.

Description

technical field [0001] The invention relates to the technical field of quality detection of printed circuit boards, in particular to a micro gap detection device, method and system based on industrial equipment. Background technique [0002] With the continuous maturity of optical imaging equipment and the rapid development of computer vision technology, it has become an emerging development trend to use hardware equipment and software algorithms to freely match and combine in the field of PCB inspection to coordinate and complete efficient and high-quality inspection tasks. [0003] In view of the miniaturization and integration development trend of electronic product chips or the high-precision micro-gap of industrial equipment, the requirements for PCB are urgently reflected in the multi-layer and dense wiring of PCB. High-precision, thin wires, high density, and small spacing are developing in the direction of development, which leads to the fact that the characteristic ...

Problems solved by technology

[0004] At present, the detection methods of PCB line width and the high-precision micro-gap of industrial equipment mainly include manual visual inspection, automatic X-ray inspection and automatic optical inspection, but they are limited by the refinement of the circuit, the diversification of factors affecting etching, Diversification of PCB boards or micro-gap products to be tested and the background environment lead to poor detection results. The types and scope of application of PCB boards or micro-gap products to be tested are not wide enough, and the practicability and adaptability are poor, especially for line width burrs. The detection method has not yet been systemized. However, in the actual measurement at the customer site, for different PCB boards or products with small gaps to be tested, sometimes low light source lighting is required, and sometimes high light source is used. At present, there is no different light source irradiation for PCB board or A technical solution for image processing of products to be tested with tiny gaps
